I think its bad news to drag an anchor so you can "boondog"...Reds, Reds and more Reds. There whats gonna keep us fishen. Potter you know your river intimately enough to know were the reds are for all species that inhabit that system so its not to bad probably, plus that river dosent get the pressure of the other rivers so you can probably afford a few mishaps too, but the occasional weekend warrior or new guy to the other rivers wont know the river good enough to make sure he or she isnt killing reds of the previous spawners.
I use a Minn Kota (NO GAS MOTORS)trolling motor on my driftboat (only on rivers were I compete with sleds), and it works awesome.
Just another option that can help in many other ways too...
Just make sure its legal for that river or species.

Again: I'm not picking on anyone either, just trying to show all asspects and offer a option that is a alot more Fish freindly...
